Problems solved by technology

However, if the automobile is moving at a high speed while in the internal circulation mode, the exterior air pressure applies force onto the external air entry (320), partially opening the air intake door (600) that was shielding the external air entry (320), and causing the entry of external air through the opening crack.
Consequently, the opening crack suctions in air pressure and causes not only the abnormal noise (air current noise) problem, but decreases air/heating functioning in the automobile HVAC system.
Furthermore, when the automobile is on external air intake mode, the ...

Embodiment Construction

[0015] The attached FIG. 3 illustrates the invention's applicable example of a door fixation apparatus and its related devices that attach the air intake door to the HVAC system.

[0016] As shown, an air intake case (40) is mounted on the HVAC case (30) to which a blower (10) and an evaporator (20) are installed to draw vehicle internal / external air, and this air intake case (40) is installed with an air intake door (1) that opens and closes the ventilator selectively for internal air entry (51) and external air entry (52). This air intake door (1) is operable in the opening / closing of the above internal / external entry (51,52) by connecting to the actuator (80) through the lever (60) and link material (70), when the actuator (80) is activated. Also, the actuator (80) is connected to the controller (2) so that the vehicle operator can control its activation accordingly. The controller (2) consists of a general microcomputer.

[0017] This invention's door fixation apparatus is comprised...

Abstract

The present invention relates to a door fixation apparatus for a vehicle air conditioner that is capable of preventing various doors or dampers that are installed in an air conditioner from partially opening due to wind pressure when a vehicle is operating or an air conditioner is operated in a state that the doors or dampers are closed. The door fixation apparatus includes a magnetic body that forms at least part of a ventilation opening and closing of the door of the vehicle air conditioner; an electromagnet that is installed adjacent a ventilation opening so that at least part of the magnetic body of the door is magnetically adhered to the electromagnet in a blocking position of the ventilation opening; a power source that supplies the current for magnetizing the electromagnet; and a controller to judge the opening and closing state of the ventilation opening and control a current supply of the power source.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a door fixation apparatus of automobile air conditioner technology, which prevents the movement of the various doors (or dampers) by wind pressure that are installed in an air conditioner air intake apparatus or duct to control the internal / external air changes and the wind amounts. BACKGROUND OF THE INVENTION [0002] The automobile's HVAC (Heating, Ventilating & Air Conditioning) system for the cold / warm air control comprises the heat exchanger and blower units. It is operated by flowing cold / warm air or ventilation through the duct that is connected from the vehicle's exterior to the interior. [0003] The attached FIG. 1 illustrates an air intake part of this HVAC system to which an evaporator (100), situated in the HVAC case (200) supplies the internal / external air inward. As shown, inside of HVAC case (200) is installed with an evaporator (100) and a blower (400) in the direction of internal / external air entry (310,320...
